I have just set myself up a test board to experiment with C-Bus units for the first time. As my first problem was the 12 v power pack supplied with a Network Interface was not supplying any voltage, I realised I was off to a bad start. After connecting another supply & connecting to my computer via network cable, the Network Int. established a good link and confimed that the unit has connection via C-Bus Communication Server . I am unable to scan my network as an error occurs saying PC Interface not detected. As I understand a Network Interface should act as a PC Interface in this situation. Any help would be appreciated.
